   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Routine code that identifies the symbiont routine to be replaced
   by a user service routine. The code argument is the address of a
   longword containing the routine code.

   Some routine codes identify routines that are supplied with the
   symbiont; when you specify such a routine code, you replace the
   symbiont-supplied routine with your service routine.

   Two routine codes identify routines that are not supplied with
   the symbiont; when you specify such a routine code, your service
   routine is added to the set of symbiont routines.


   Each programming language provides an appropriate mechanism for
   defining these routine codes. The following pages list each
   routine code in alphabetical order; the description of each
   code includes the following information about its corresponding
   routine:

   o  Whether the routine is supplied by the symbiont

   o  Whether the routine is an input, formatting, or output routine

   o  Under what conditions the routine is called

   o  What task the routine performs
